Calculate how much you can expect to pay for window installation and replacement in Alpharetta, GA using our customized window cost calculator.

How Installing Energy-Efficient Windows in Alpharetta Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:
- Better temperature control in your home: Living in a chilly city like Alpharetta can often mean needing your heater to keep your home cool. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $362 annually on your energy bills in Alpharetta.
Estimated Cost of Window Replacement in Alpharetta
Windows come in varying purposes, shapes and styles, so costs and services will vary remarkably depending on your project. Below, we describe the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Typically, Alpharetta homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost you varies based on several factors, like the location of your home, type, material, size, number of windows and more.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Getting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step when planning a window replacement is to clarify whether you should get a full-frame or pocket installation.
A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Alpharetta
EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Alpharetta, we gave more points to companies that cover the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Alpharetta.
Work Quality
When it comes to new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Alpharetta's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Alpharetta window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Alpharetta, GA Window Replacement FAQs
What is the average cost to install windows?
The national average cost to replace a window is around $600 but can range from $200 to $1,200, depending on several factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should hire a window installation company whenever you want to upgrade your windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
